IMPROVEMENT- IN LASTlNG-MACHINES.

Specification forming part of Letters Patent No. 44,916, dated November 1,1864.

To all whom it may concern:

Be it known that I, WILLIAM E. Frscnna, of Boston,in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Machines for Lasting Boots and Shoes; and the following is a clear, full, and exact description of the same, taken in connection with theaecompanying drawin'gs.

In the construction of lasting-machines substantially rigidjaws for holding the leather to the last and rigid flanges extending'over from the jaws for breaking down the edges of the leather over and upon the bottom of the last i have been used as necessary devices; but as rigid jaws cannot well be made-so to fit theform of the last as to hold the leather closely to its edge, the result has heretofore beenth'at when the flanges broke down the leather over and upon the bottom it was crowded away more or less from the edge and side of the last,

and so failed of a smooth and perfect tit; and

'the employment of indie-rubber or other. equivalent elastic cheeksor linings to the jaws, so constructed that while in closing up they conform to the shape of the last they operate so as to press the leather up to and crowd or draw it down upon the last, and hold it snug while the flanges break it down over the bottom.

. In adapting my invention I have used substantially the machine invented by Purinton and improved by WVells.

The following,'in connection with the drawin gs, is afull description of my invention.

Figure leis a top view of my machine, with Fig. 2 is an end view, with the toe-jaw removed. Fig. 3 is a sectional'view of a rubber cheek in three different positions assumed in lasting.

A is the table, mounted upon a frame, B. O

is the heel-jaw, which is stationary on A. D

is the toe-j aw, hinged upon the table A. E E are clamps pivoted at e e to the table, E E are side jaws, attached to the clamps. F is a perpendicular rod midway the frame, having a wedge-shaped head, F, between the lower arms of the'clamps at its upper end, and havin g itslower end attached to a long foot-lever, G, which ispivoted at-one end to a projection, g, on one of the feet of the frame, and at the other end catching into a notch in a projection, H, on the other foot of the frame when pressed down. I is a slot in a brace of the frame, through which the cam wedge-rod F passes. Kis a pin having. its lower end, J,

fastened to the table or frame and its upper endinsertednintoahole in lhe'last for -sup-s porting it in place. This is in working machines made adjustable. L is an iron clasp or bar fastened to the heel-jaw at L and brought round behind the toe-jaw. M is athumb-serew passing through the toe-jaw D and through a female screw inL, for the purpose of advancing or receding the hinged toe-jaw to or from the last. N is the last, supported upon the rod or pin K. O P Q are my rubber cheeks or linings of the jaws, fastened to them by screws. R S T are the flanges to the jaws.

The method of operation is as follows: The toe jaw l) is turned back a little on its hinge. The foot-lever G is raised, and-"the side jaws, E E, are thrown open. The last, with its insole and upper, is placed upon the pin K within the jaws O D E E. The lever G is then pressedrdown with the foot and confined in the notch of the projection H. In pressing down the lever the wedge-cam F'crowds out the lower arms of the pivoted clamps E E, and the jaws E E are closed up. The toe-jaw D is then closed up by turning thejthumbserew M. In closing the jaws the rubber checks 0 0 press against the sides of the upper-leath lf,

rubber cheek, as used by me, as it'iappearsjsubstantially before, during, and after the closing up of the jaws. The best form for these checks I have found to be such as I represent in my drawings and machine, being strips-of rubber of a triangular shapevertijcally, and the object of this is that the upperpart-imay'reach or crowd up and retreat as it is pressed onto the shoe, andso not only conform to the shape of thelast and press against it, but continue that conformation and pressure up to the edge of the last and up to the flange as it breaks down the upper,at the same time operating so as to push or draw down the leather over the last.

ion will not accomplish this end. For ordinary purposes in the machines I have used, these cheeks need not be applied,

A mere cushexcept upon the side jaws. Instead of the jaws being moved up to the last, as is necessary where the flanges are. made rigid upon or form a part of the jaws, the jaws may be lined with rubber, and then, being placed in position, the last, with its upper, may the crowded down into the lined jaws, and then the flanges, where they are needed, be made to move over-and break down the leather.

1 do not new claim a mere solid elastic padv intended to operate only within the hollow of the last; but

What 1 do'claim, and desire to secure by Letters Patent, is-

The application of rubber or other equivalent elastic oheeks orlinings to the jaws or *clamps of lasting-machines, substantially as and for the purposesdescribed.
